Modular Bird Feeder consists of 3 or more parts. Print each one upright without supports. You will need a top, a base and as many center sections as you wish. Run a wire through the hole in the lid to make a hanger. Each section screws together via standard mason jar threads. these are long prints, but not too complicated. Add adhesion if you wish, but I had no trouble with PLA. Of course, PLA and outside doesn't mix so well, so I'll print to next one in ABS or PETG. The files marked WM are wide mouth threads and not compatible with the others. Either print 3 regular, or 3 WM. The wide mouth is pretty big.

I am reducing the distance between the perch and feeding hole and will update soon.
